It is physical. The wire changes shape, but it is still made of the same materials.
When a candle is burnt a physical AND chemical change takes place. Its a physical change when the wax is being melted because the chemical structure has not change, meaning it cannot be a chemical change. Its also a chemical change because you are burning the string. When you burn something the chemical structure DOES change, meaning it is a chemical change.
A physical change
Physical change of the paint, not the door.
the difference between a physical change and a chemical change is that a physical change is usually reversible whilst a chemical change is not reversible.
Physical... chemically, it's still the same substance,
Explain the difference between chemical change and physical change, and provide examples of each. Define chemical change and physical change, and provide examples to illustrate. Differentiate between chemical change and physical change, and give examples to clarify the distinction.
both physical and chemical change occur
its physical change.to explain,the conversion of solid to liquid is physical

Its also a chemical change because you are burning the string. When you burn something the chemical structure DOES change, meaning it is a chemical change.
It is a physical change because when you have a chemical change it changes the properties and makes it into a new thing, and it can't be reversed. Physical changes are usually just changes of states (solid, liquid, gas) and a physical change can be reversed.
A physical change
Melting: change of phase, a physical phenomenon without change of the composition. Burning: a reaction of oxydation, a change of composition - a chemical change.
Both
Breaking of stone is a physical or chemical change? Explain.
Physical change of the paint, not the door.
it is a chemical change
An acid is a chemical compound, not a physical or chemical change.
